Earth Day 2010: Top 10 Deals, Perks, Freebies

If getting down and dirty in a neighborhood garden isn't your thing, merchants across the country have come up with plenty of other ways for you to celebrate Earth Day today.

In honor of the 40th anniversary of the worldwide day of environmental awareness, companies are offering a slew of perks and discounts.

"We're seeing more than we saw last year," said Luke Knowles, founder of the deal-aggregating blog Coupon Sherpa. "Companies just want to seem like they're environmentally-friendly, so they're trying to take advantage of this as much as possible. If there's an opportunity, merchants will jump on board to take part."

With Amazon's help, you can read yourself to a greener world. Through the online retailer's Read, Reuse, Recycle program, you can save up to 34 percent on Earth Day books for children and adults.

Several states have chosen to launch their programs on Earth Day. For details on your state's program, click HERE.
